Abstract

A multiphase clock and data recovery (CDR) circuit having a novel rotational bang-bang phase detector (RBBPD) is demonstrated. The proposed 1/4-rate RBBPD decides the locking point using a single clock phase among sequentially rotating 4 clock phases. With this, our RBBPD has significantly reduced power consumption and chip area. A prototype 10-Gb/s 1/4-rate CDR with RBBPD is successfully realized in 65-nm CMOS technology. The CDR consumes 5.5 mW from 1-V supply and the clock signal recovered from 231-1 PRBS input data has 0.011-UI rms jitter.
